Dahlia plant named ‘Balnovrese’

ABSTRACT

A new and distinct Dahlia plant named ‘Balnovrese’, characterized by its yellow inflorescences with red accents and vigorous upright mounded growth habit is provided.

Latin name of genus and species of plant claimed: Dahlia pinnata.

Variety denomination: ‘Balnovrese’.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct Dahlia plant, botanically known as Dahlia pinnata and hereinafter referred to by the cultivar name ‘Balnovrese’.

The new cultivar originating as the product of the open pollination of plants from the seed variety Dahlia pinnata series ‘Figaro Improved’ (unpatented). The new Dahlia was discovered and selected as a single flowering plant from within the progeny of the above stated open pollination at Elburn, Ill. The new cultivar was initially designated PAS12202-8.

Asexual reproduction of the new cultivar by terminal or stem cuttings taken during 2001 at West Chicago, Ill., has demonstrated that the characteristics of the new cultivar as herein described are reproduced true to type through successive generations of such asexual propagation.

SUMMARY OF THE INVENTION

It was found that the cultivar of the present invention:

(a) forms double inflorescences with yellow ray florets with red accents;

(b) exhibits an upright mounded habit; and

(c) exhibits a vigorous growth habit.

‘Balnovrese’ has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and day length without, however, any variance in genotype.

The new cultivar of the present invention can be compared to ‘Margaret’ (U.S. Plant Pat. No. 6,769). However, in side-by-side comparisons, ‘Balnovrese’ exhibits smaller inflorescences with fewer, smaller ray florets. The flowers of ‘Balnovrese’ are bicolor whereas those of ‘Margaret’ are solid.

BRIEF DESCRIPTION OF PHOTOGRAPH

The accompanying photograph shows as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical inflorescence and foliage characteristics of the new cultivar. The plants were grown for nine weeks in a greenhouse at West Chicago, Ill.

DETAILED BOTANTICAL DESCRIPTION

The chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England. The color values were determined on Nov. 21, 2001 in West Chicago, Ill. The readings were taken between 10:00 and 11:45 p.m. under natural light conditions. The following observations and measurements describe plants grown in West Chicago, Ill., for nine (9) weeks after planting of rooted cuttings. The plants were produced from cuttings taken from stock plants and were grown in a double polycarbonate covered greenhouse under conditions comparable to those used in commercial practice. The plants were grown while utilizing a soilless growth medium and maintaining temperatures of approximately 65° to 70° F. (18° to 21° C.) during the day and approximately 60° to 65° F. (15° to 18° C.) during the night. Light levels of 4,000 to 6,000 footcandles were maintained. Plants were pinched at three weeks after planting.
